Ludovic,

Thx for feedback.

Re Debian: I'm using Debian Lenny, with gnat-4.1 (4.1.2-8)
and this *is* (still?) providing Deep_Tag_Finalize; I suppose
that will soon change then.

I'll follow up on the advise to delve into it: the situation
may change apparently. Not the most easy part of Ada to delve
into though. We'll see.
